+/**
+ * Defines an annotation object for strings that require plural forms.
+ *
+ * Note that the return values for both 'singular' and 'plural' keys needs to be
+ * passed to
+ * \Drupal\Core\StringTranslation\TranslationInterface::formatPlural().
+ *
+ * For example, the annotation can look like this:
+ * @code
+ *   label_count = @ PluralTranslation(
+ *     singular = "@count item",
+ *     plural = "@count items",
+ *     context = "cart_items",
+ *   ),
+ * @endcode
+ * Remove spaces after @ in your actual plugin - these are put into this sample
+ * code so that it is not recognized as annotation.
+ *
+ * Code samples that make use of this annotation class and the definition sample
+ * above:
+ * @code
+ *   // Returns: 1 item
+ *   $entity_type->getCountLabel(1);
+ *
+ *   // Returns: 5 items
+ *   $entity_type->getCountLabel(5);
+ * @endcode
+ *
+ * @see \Drupal\Core\Entity\EntityType::getSingularLabel()
+ * @see \Drupal\Core\Entity\EntityType::getPluralLabel()
+ * @see \Drupal\Core\Entity\EntityType::getCountLabel()
+ *
